Dual PSU's for WC setup... How does it work?

post #1 of 5
Thread Starter 
Hi all. So, another question (thanks for putting up with them, lol).

Some loops have 2 PSU's. One for the mobo and some other things, one for the WC loop. How exactly does this work?

I mean, with a Motherboard you can attached a power switch, or use the power button on the mobo to cycle the PSU on. When you have a WC loop, how do you get the 2nd PSU turned on when you hit the power switch for the mobo? I know there are those dummy plugs/paper clip mods to trigger the PSU on, but is there a better way?

I'm just curious is all.

Thanks!

You need to tie the green wire of the ATX power connector to each other so both the power supplies get the power on signal from the motherboard. You can easily do it by hand or just buy an adapter. http://www.frozencpu.com/products/11742/cpa-167a/ModRight_CableRight_Dual_Power_Supply_Adapter_Cable.html?tl=g11c413s1220

I believe something like this would be the best solution for having two power supplies power on at the same time.

I realize you started the thread just for an education, but just to recount my personal experience, I had the exact same question as you did. I was wanting to run my components off of my PC Power & Cooling 750w and run the WC setup off of a Antec 350w I have. After doing a lot of research, I found out my 750w was more than plenty to run my sig rig and my WC with 6 fans + some cold cathode lighting. If you are using the 850w, you are not going to have an issue unless you run some power hungry nvidia cards.
